It absorbs minor shaft misalignment and dampens vibration between the motor and pump, reducing wear on bearings and mechanical seals. The coupling is rated for use with 1\/2, 3\/4, and 1 HP motors and accommodates clockwise (CW) rotation. It fits shaft combinations of 1\/2 x 1\/2, 1\/2 x 5\/8, and 5\/8 x 5\/8 inches. Licensed plumbers, hydronic heating technicians, and mechanical contractors typically install this part during pump motor replacement or coupling inspection service calls.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial hydronic heating applications where in-line circulators are used to move hot water through the distribution loop. It is manufactured by Westwood Products under the Spiralink product line and is intended for systems running CW-rotation motors in the 1\/2 to 1 HP range. Its flexible spring design tolerates small angular and parallel shaft offsets without transmitting shock loads to pump components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible spring design absorbs vibration and minor shaft misalignment\u003c\/li\u003e\n  \u003cli\u003eFits three shaft size combinations: 1\/2 x 1\/2, 1\/2 x 5\/8, and 5\/8 x 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003eRated for 1\/2, 3\/4, and 1 HP motors\u003c\/li\u003e\n  \u003cli\u003eClockwise (CW) rotation orientation\u003c\/li\u003e\n  \u003cli\u003eCompatible with Taco 121-138 Series in-line circulators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use with Taco 121-138 Series in-line circulators and 1\/2, 3\/4, and 1 HP motors.

Shut down the boiler and isolate the circulator from system pressure before removing the existing coupling. Verify motor shaft rotation direction is CW before installing this coupling, and confirm shaft diameter matches one of the supported size combinations before proceeding. Follow all applicable local mechanical codes during service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Flexible Spring Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size Combinations\u003c\/strong\u003e: 1\/2 x 1\/2, 1\/2 x 5\/8, 5\/8 x 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor HP Rating\u003c\/strong\u003e: 1\/2, 3\/4, 1 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotation\u003c\/strong\u003e: Clockwise (CW)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Westwood Products\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BECKETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SPIRA-H24-34\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BECKETT","offers":[{"title":"Default Title","offer_id":51383297737010,"sku":"SPIRA-H24-34","price":66.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670542.jpg?v=1782592609","url":"https:\/\/voomisupply.com\/products\/beckett-spira-h24-34-flexible-spring-circulator-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
